1,412,160., I p T 15 "Application filed w ys; To all whom it mayconcern: j I Be it known that I,.ANeUs J. Bo-YD, sub ject ofthe King ofEngland, residing at Dedham, in the county of Norfolk 'andState ofMassachusetts, have invented certain new. 1 and useful Improvements inStop Signals.

for Automobiles, of which the following-isa specification, referencebeing-had to the accompanying drawings. l

. It is the 'purposeof the present invention toprovide a device of thisgeneral character particularly adapted-for use on automobiles, trucksand the like for indicating to the chauffeur of the automobile in therear, that the forward automobile will stop Another purpose is toprovide a signal of this kind consisting of rocking tubular rods,mounted on the side of the automobile or truck, and provided with arightangle ex-. tension having a stop signal, whereby when the rod isrocked, the'right angle extension will be extendedlaterallyfrom the sideof; the automobile, so as. to indicate. thatv the forward automobilewill stop, or turn, as the signal is to beuSedwhenmak1hg allilluminating omeans, .forr lighting. up the stop signalat night,so1thatit may be readily read tical form for commercial purposes, the .in-,-

vention may be susceptible of changes, and the right to these changes isclaimed, provided they are comprehended within the scope of what isclaimed.

The invention comprises further features and combination of parts, aswill be hereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a' view in elevation of the improved stopsignal including the rocking rod, as being mounted instrap bearingscars'ror SIGNAL. Fon AUroMoBILEs. i

The bearings for the the tubular rod,which may be, mounted in" the supporting rod 3,:whi'ch constitute 5 iany suitable part f of the automobile, forthe purpose of supporting thestop signal. Each ra y be genough to fitany sizefl 1 of rod 3, and isbent at 1 to' d id an Q'ffse-t bearing,iwhich overlies the'tubularrocking rod.' *Itwill be noted'th atone of the strap bearings 1sdisposed in aposition under a handle 5 of the rocking rod- 1, to preventthe rod 1 from displacement downwardly, that P;

is from graduallymoving downwardly, due toithe constant rotatingof therod for signalling purposesu The handle 55 extends at rlghtangles-to'the tubular'rod 1, andliesin a plane parallel with and belowthe right angle extension 2.

The extension 2 terminates in an upstanding arm 6 terminating in a plate7, to which a correspondingly shaped plate 8 is bolted or otherwisesecured by means of the. bolts 9. i

A suitable casing 10 is carried by the plate 1r 8, and mounted in and'supported by the casing 10 is a conventionalform of electric light lamp11.

s ob A suitable switch lever or arm 12 is operatively connected to thebase of the lamp in the usual manner, for closing and opening thecircuit, operating the lamp.

A band 13 is mounted permanently in any suitable manner upon the casing10, and has an annular flange 14, to limit the downward for the purposeofg movement of the housing 15, which telescopically fits the band 13. Asuitable plate 16 is fastened to the housing by soldering,-

brazing or by any suitable means, and has V 75, rocking-rod, as in Egures1and3 each com? 1 Q PIISGS a 111613511110 trapI2 wha k 'fg e b 1' Vor wires 19 and'2O pass through the tubular rocking rod 1 and areconnected in any suitablemanner to the lamp. These wires or leads are inturn connected to a conventional form of battery 21, for supplyingcurrent to the lamp. The leads or wires may be protected from a positionadjacentthe battery 21 to the lamp, by means of a plurality of tubes 22through which the wires or leads may pass. A portion of one of thesetubes is illustrated in Figure 2 as being threaded to the tubularrocking rod 1, and owing to the threaded connections, the tubularrocking rod is capable of a half or quarter turn so as to move theextension 2 laterally from the automobile, and then return it within orto the side of the automobile. The sections of tubes 22 which are to beused to house the wires or leads below the rocking rod may be 7 securedfixedly to any suitable part of the automobile, so as to hold the tubessecured against movement, so that when the-tubular rocking rod isoscillated, the threaded connections will remain relatively the same.

In the use of the device, the tubular rocking rod 1 is arranged sothatits extension arm 2 will lie normally within the car body, or adjacentthe side of the body, so that the stop signal cannot be seen. Howeverwhen the ohaufieur desires to indicate to the chauffeur to the rear, orto signal the traffic policeman that it is the intention tostop or turnthe automobile, the handle 5 may be grasped, and the tubular rod 1rocked,which of the automobile for rocking movements, means topreventdownward axial movement thereto, said rod terminating at itsupper end in a lateral portlon having an upstanding part, the terminalof which being pro:

vided with a circular plate, a housing for electrical connections to abulb detach'ably mounted upon said plate and mov able axially with theupstanding portion, a bulb housing mounted on the first housing, andprovided with a signal plate on the second housing extending laterallyin a plane paral lel with the lateral part of said rod, and

provided with directions thereon, said bulb/- housing having an opening,through which the light rays from the bulb illuminates the directions onthe signal, said rod being tubular, for the reception of conductorswhich operatively connect with the electrical connections for the bulb.

2. In an automobile signal, a rod mounted for rocking movements inbearings of a perpendicular portion of an automobile,said rodterminating at its upper end, a lateral oflset part in a plane parallelwith thebody of said part, said offsetpart having at its upper end acircular plate,.a housing for electrical connections to a bulb,detachably supported on said plate, a bulb housing mounted on the firsthousing, a lateral signal on the bulb housing and having directionsthereon, said bulb housing having an opening, through which the lightrays from the bulbillumi- V nates the directions on the signal.
